Application Afiled. July 23, 1918, Serial No. 246,299. Renewed August 1'8, 1919. ASerial No. 318,313.l

To all whom it may' concern: Y

Be it known that l, Aiinxis JAiiovLurr,` a citizen of Russia, residing ait -the city and county of San Francisco and `State ofv California, have invented 'new i and useful' Improvements in Vehicle-Tires, of which the following is a specification.

HrlY-his invention relates vto a vehicle wheel', and Vparticularly pertains to a pneumatic4 tire therefor.

The object of the invention `is to Vprovide a demountable tire construction which 'is' simple, practical, easy of construction, puncture-proof and easy riding, with interchangeable parts. To this end I provide a casing. in separable sections, -in conjunction with suitable inner and outer rims united to form a complete casing and tread, all as will be Amore fully set forth and described hereinafter.l

Hav-ing referenceto the accompany-ing' drawings: f .Y y

Figure l is a viewin transverse section disclosing the vital elements of the present invention and their correlation to each other and the vehiclewheel. Fig 2 is a fragmentary view in section Y and elevation, illustrating the interlocking ends ofthe expansion ent device.

lFig. '3 is a fragmentary View in elevation,

ring used inthe presillustrating the ends of ythe ring as locked.

Referring Amore particularly to the drawings, 10 indicates the `felly of a wheel sup.

ported upon suitable spokes 11. Mounted L .siliency depending upon .the thickness of Vtion, that is, the riin is provided with a central annular body portion, the opposite marginal edges of which are turned to form clencher flanges V13 and 14:. These flanges are adapted to receive c lencher beads 15 and 16 of opposite casing parts y17 and 1 8. These parts are of substantially the same sectional contour as the ordinary pneumatic tire casing. Ilowever, in the present instance they are separated to form complementary halves disposed along the opposite sides of a pneumatic tire tube 19 and extending entirely around the rim. The outer terminating edges of these halves 17 and 18 are formed with clencher beads 2O and 21, respectively. These beads are engaged by an outer clencher rim 22 which is formed with inturned ciencher flanges similar to the outer edges of thecasingparts together.I

il-anges and '14 andwhich flanges bind the Y Thev outer .clencher rim 221is provided tinuous Vshaped grooves 25 extend entirely around the outer faceV of the rim in paral.y

lel relation to each other. ltrwill thus be .further secure the tread upon the rim and' Ato Vprevent it jfrom creeping a series of conseen that. 'when' the 'composition becomes embedded within these grooves 'it will interlock to `'forin a rigid combination therewith'.

Tlieinner circumference Vofthe outer V,rim is formed withv a central circumferential flange 26 which is so formed as to exactlyy i register with the space between tli'eadjacent ends ofthe clencher beads ofzthej casing. Thisflange is adapted to be borne against anexpansion ring y.27 by which i' interlocked relation to their flanges. vrllhe 27 extends continuouslyv around the inner circumference of the 'clencher rim` 22 and is `.prefeiably formed 4of .spring steel which isV also `.the case with the outer cl'encher rim, thus insuring that'rthe ring andV rim will have a slightdegree of retheV spring steel to absorb the loca-lniinor the rclencher beads are positivelyfrheld in road shocks-and thereafter impart the or v shocks to the pneumatic casing and tube] The ring 27 is of angular ,formation when considered in transversesection, thatis, the. v`

outer face ofthe ring is adapted tov conform to the converging 'surfaces of the tire beads and to further' registerl lwith circumferen-` t-ially extendingv grooves 2S in these surfaces. The grooves 2S are spaced in relation to eachother and receive protruding beads 29l which continue around theouter surface of'` ioo the ring and interlock with the recessesjto prevent the outer casing part-s from pulling away from their clencher flanges and ,in-1

Vof the casing members willV be positively turningagainst the tube. :Due to the .wedgei iio 4 held in relation to the outer clencher rim. It is desirable to form the locking ring in a manner to insure its ready removal from position when desired'and the ring has therefore been transversely split in its circumference. The abutting ends of the ring at this split have been formed one with a lockino tongue 30 and the other with a com- D b 1 plementary recess 31 into whicn the tongue projects. Due to this construction the ring will operate as acomplete annulus and its ends4 may be readily separated and contracted to effectits removal.

In using the present invention it will be readily understood that the two halves of the clencher lcasing may be positioned around the inner ring 12as in common tire construction. l A pneumatic tube may then be placed in proper relation to vthese halves .v

the shook will be transmitted to the casing andthe pneumatic tube, as is common,

through the resilient lock ring 27 and clencher rim 22.

yIt will thus be seen that the structure here disclosed aEords a simple form of tire which may be readily manipulated to allow vaccess to the pneumatic tube therein as well as to provide ease of application to a vehicle wheel. ,c

While I have shown the preferred form of my invention as now known to me, lI

wish it understood that various c hangesV in the combination, construction and arrangement of parts may be made by those skilled in the art without departing from the spirit ofrny invention as claimed.

Having thus described my invention, what I claim .and vdesire to secure by Letters Patent is-- j I Y 1. In a vehicle tire, a casing formed in halves, an outer riin having side flanges to grip thel peripheral parts of the casing halves, a central inwardly projecting flange on the inner face of said riin and having its opposite sides formed to abut the free edges of the casing halves, and an expansion ring of approximately angular cross-section having the center of its outer faceseated on said central flange of the outer rim, said ring havingperipheral beads on each side thereof received in grooves provided therefor in the inner faces of the casing/halves j and the free side edges of the ring lying opposite to and confronting the free side edges of the V'flanges of the outer rim so as to form contracted neck portions therewith.

2.*In a vehicle tire, a casing formed in halves, an outerrim having side flanges to grip the peripheral parts Vof the' casing halves, a central inwardly projecting flange on the inner face of said rim and having its opposite sides formed to abut the free edges of the casing halves, and an expansion ring of approximated angular cross-section hav- Ving vthe center ofY its Vouter face seatedon 4said central flange of the outer rim, the free side edges of the ring lying opposite to and confronting the free side edges of the side tracted neck portions therewith.

3. In a vehicle tire, a casing formed in halves, an outer rim having side flanges to grip Vthe peripheral parts of the casing halves, a central inwardly projecting flange on the inner face of said rim and having its opposite sides formed to abut the free edges of the casing halves, -and an expansion ring of approximately angular cross-section havthe center of its outer face seated on saidk central flange of the outer rim, said ring having annular circumferential proflanges of the outer yrim so as to form conj ections at Vthe free sides thereof which projections extend toward Yand lie oppositeto the free side edges of the flanges of the outerring so as yto form contracted neck portions therewith.

4 In a vehicle tire,'a casing for-inedin halves, an outer rim having side flanges, the free edges of which extend into the outer faces of the peripheral parts of the casing halves, and an expansion ringY of angular cross section engaged with the inner faces of the peripheral parts ofthe casing halves, said ring having flanged edges extending outwardly toward the periphery of the casing and approximately radiallythereof into the inner faces of the peripheral parts of the casing halves opposite to the free edges. of

ico

the side flanges of the outer rim whereby u to forni contracted portions in the casing halves.

,75. `In a vehicle tire, a casing formed in halves, an outer riin having sideflanges to grip the peripheral parts of the casing halves, and ank expansion ring engaged with the inner faces of the peripheral parts of the casing halves, said ring being split and 'having a locking tongue on one end and having a recess in its opposite end receiving the tongue whereby to completely house the latter.

In testimony whereof I have hereunto set hand in the presence of two subscribing witnesses. v c
